Network Virtual Serial Ports Driver is an advanced
utility, the purpose of which is to emulate null-modem
cable on computers located in a TCP/IP LAN or
connected to the Internet. In other words, with VSPD
Net you can create any number of pure virtual serial
ports in your system, which will be connected over
TCP/IP network to another computer via virtual null-
modem cable. Real serial ports will not be occupied.
Example: You have two computers, host1 and host2 for
example, connected with TCP/IP networking. You can
create virtual serial port COM5 on host1 and virtual
serial port COM6 on host2 and connect those ports to
each other via virtual null-modem cable. Everything,
that application on host1 will send to COM5 will be
received by application on host2 at COM6, and all that
application on host2 sends to COM6 will be received by
application on host1 at COM5.
